I would recommend the Samsung 840, they are highly recommended by alot of people and has been said to be fastest on the market now (don't quote me, I've just heard and never seen benchmarks). I have two Mushkin Chronos Deluxe's and they are pretty fast, but the first 4 SSD's I got from them went faulty within a week of having them. (Although, the Deluxe's, that I got after the first 4 regular chronos's, has been working like a dream for the past 8 months)
